Decomposition of \(X\) exhibits a rate constant for \(0.05\, \mu g/year\). How many years are required for the decomposition of \(5\, \mu g\) of \(X\) into \(2.5\, \mu g\) ?
- A \(50\)
- B \(25\)
- C \(20\)
- D \(40\)
Answer & Solution
Correct Answer
(A) \(50\)
Step-by-step Solution
Detailed explanation
According to unit of rate constant it is a zero order reaction then half life of reaction will be \({t_{1/2}} = \frac{{{C_0}}}{{2k}} = \frac{{5\,\mu g}}{{2 \times 0.05\,\mu g/year}} = 50\,years\)
